ABSTRACT
Anacroneuria tucuman sp. nov. is described from two males collected in Tucuman Province, Argentina, and a lectotype is designated for Anacroneuria fumigata Klapalek, a Brazilian species. The first Argentine records are given for A. atrifrons Klapalek and A. handlirschi Klapalek, and a few additional specimens of A. impensa Jewett, A. trimacula Jewett and A. uyara Froehlich are recorded. A checklist for 24 Argentine Anacroneuria species is given.
Keywords: Anacroneuria, Plecoptera, Perlidae, Brazil, Argentina, Lectotype, new species, new records
INTRODUCTION
Anacroneuria fumigata Klapalek is the last of 17 Anacroneuria species proposed posthumously by Klapalek (1922). Specific information on the composition of the type series is not given, but specimens deposited in the Berlin Museum and the Klapalek collection are indicated, and a range is given for body length and for wingspan, suggesting multiple specimens were included. While visiting Schlitz in 1988, I had the opportunity to examine the male terminalia of one of the syntypes from the National Museum, Prague, while the specimen was on loan to P. Zwick. Sketches made at that time were shared with C. Froehlich to assist in possible recognition of the species should it be rediscovered. Despite significant study of Brazilian Anacroneuria in the 25 year interval, apparently no specimens of A. fumigata have been discovered (Baldin et al. 2013; Bispo & Froehlich 2004a, b; Bispo et al., 2005; De Ribeiro & Froehlich 2007; Froehlich 2002, 2003, 2004, 2007, 2008, 2010b; Ribeiro-Ferreira & Froehlich 2001). Consequently, I provide the following redescription
of male genitalic characters and designate a lectotype for this distinctive species. In addition, I have studied a few Anacroneuria specimens from Argentina over the past 25 years. Because there are relatively few published Argentine records in the literature, I take this opportunity to describe a previously unrecognized species and to provide records for additional species. These additions bring the list of Anacroneuria species reported for Argentina to 24, however two of these are nomen dubia, and two others were considered by Illies (1966) as "Species inquirenda". Hopefully this small contribution will encourage continued collection and study of Anacroneuria at the southern extremity of its range.
MATERIALS AND METHODS
The abdomen for specimens was clipped near midlength and the terminalia brought to a boil in 10% KOH for a few seconds. Boiled terminalia were removed to dishes of distilled water and the internal viscera carefully removed; the aedeagus of male

RESULTS AND DISCUSSION
Anacroneuria atrifrons Klapálek
Anacroneuria atrifrons Klapálek 1922:89. Holotype S (British Museum of Natural History), Amazon, St. Paul [Brazil, Amazonas, Sao Paulo de Olivenca] Anacroneuria montera Stark & Sivec 1998:41. Holotype S (United States National Museum), Iquitos, Loreto, Peru, syn. Froehlich (2008)
Material examined. ARGENTINA: Córdoba, Alta Gracia, La Paisanita, 17-23 February, 1984, L. Olivia, 1S, 3? (BPS). BRAZIL: Bahia, Barra, 9 December 1907, 1S (CMNH).
Comments. This species was formerly known from Brazil, Colombia and Peru (Froehlich 2008; Stark 2004; Stark & Sivec 1998; Stark et al. 2001). This is the first Argentine record and both new localities represent significant range extensions beyond the known Amazonas and Loreto area distribution.

Anacroneuria fumigata Klapálek 1922:95. Lectotype S, here designated (National Museum, Prague), Espirito Santo, Brazil
Anacroneuria fumigata: Froehlich, 2010a:156.
Material examined. BRAZIL: Espirito Santo, lectotype S (NMP).
Male genitalia. Hammer thimble shaped, height greater than basal diameter (Fig. 1). Aedeagal apex bearing upright lobes on ventral and dorsal surfaces beyond hooks (Figs. 2-4); apex slender in dorsal and ventral aspect, and slightly excavated, but somewhat thicker and irregular in lateral aspect; ventral lobe concave, dorsal lobe convex. Hooks slender (Figs. 2,
4).
Femle. Unknown. Larva. Unknown.
Comments. The Berlin syntype is said to be missing (Froehlich 2010a) and the original description does
not identify the total number of syntypes, consequently I designate the National Museum, Prague, Anacroneuria fumigata Klapalek male specimen labeled Zw# 100 as lectotype in order to provide stability for this species. The aedeagus is quite distinctive and no closely related species is known.

half of the disk and a pale area incorporated within dark region in center of disk (Fig. 5). Legs pale brown except for narrow dark brown band on distal end of femora. Wings pale, transparent; veins pale amber except for C and R veins which are very pale. Male. Forewing length 12-14 mm. Hammer a low, almost transparent bubble-like structure (Fig. 6). Aedeagal apex simple, but slightly offset from shoulders by a subtle notch (Figs. 7-9); a pair of small membranous lobes occur on the posterior margins of the apical area and an inverted Y-shaped keel with long stalk occurs on the dorsum. In lateral aspect the sclerotized area bulges slightly and is offset from the pale keel. Hooks slender (Figs. 7, 9). Female. Unknown. Larva. Unknown.
Etymology. The species name, used as a noun in apposition, is based on the Argentine province in which the type specimens were collected. Diagnosis. Only three Anacroneuria species are currently known from the neighboring province of Salta [A. arrazayalensis Orce (Orce 2003); A. marshalli Stark (Stark 2007); A. saltensis Froehlich (Froehlich 2002)] and only A. reedi (Navas) (Navas 1919), a species whose identity is in question (Illies 1966), has
been reported from Tucuman Province. The aedeagus of the new species is generally similar to that of A. saltensis but the keel in that species consists of a pair of parallel lines, the apex is not offset from the shoulders and the hammer is thimble shaped. Several other Andean species, such as A. pachacuti Stark & Sivec, 1998 have similar aedeagal shape and features but none have the combination of a slightly offset apex, a Y-shaped keel and the low bubble-like hammer found in A. tucuman.
